These and other objects may be attained by of the construct-ion illustrated in the accompanying drawings, in which:

Figure 1 is a rear elevation of e cotton chopper made in accordance with my inveze Lion. E 2 is a vertical section throu ll the axle ands lwwing the 0 eretive mechanism of the chopper in side elevation. Fl. 3 is transverse vertical seetion taken in line Will! the axle. Frg. 4 1s a (retail sectional new of r one romtin hoe shaft, and showing the l shanks in g lace. Fig. 5 is a face View of the clamp plate for holding the choppers in place.

Referring to the drawings for e more pee nicnler description of my invention, the numeral 1 designates l, e exle provided it'll a sqfiareel end 2 which fits a. hub 3 of one of the Wheels 4 so that said wheel will rotate ihe axle 1. The Wheel 4 is provided with a, hub 5 whiel'l is mounted to rotate freely upon the axle 1. Dependilw from the axle i is a yoke 6 heving horizontal sleeves 7 through which the axle 1 passes end free!" rotates therein. Stop rings 8 on the. axle prevent lateral. movement of the axle relatively-to the jfllfie. Keyed to the axle 1 is e large bevel gem Wheel 9 which meshes wiila a bevel pinion 10 mounted to rot-ate upon a stub shaft- 11 rising from a bracket 12 supported upon a shaft 13 mounted in beerin s 14 on the yoke 6. Th9 bracket 121's provioed with a washer 15 underneath the pinion 10.
